## Long description

The Three-phase energy meter OEM ProBase™ 3F-ESH-4ML 3x230/400V 100A is an accurate active energy meter engineered for three-phase 230/400 V electrical systems with a rated current of 100 A. Designed for panel mounting, the device measures active energy per phase and provides reliable consumption data for residential, commercial and light industrial installations. The meter supports standard metering functions needed for monitoring usage, supporting internal billing and enabling energy management tasks within an electrical distribution board.
Advantages
This meter delivers phase-by-phase active energy measurement with stable performance under normal operating conditions. Its compact panel-mount form factor simplifies installation in distribution boards and switchgear. The device is intended for direct connection up to the rated current and provides measurement data suitable for monitoring consumption and validating energy usage. Built with standard electrical mounting and connection interfaces, it fits common installation practices and reduces integration time.
Suitable for
 Monitoring electricity consumption in multi-phase residential buildings
 Submetering in commercial premises and retail spaces
 Energy tracking in light industrial or workshop distribution panels
 Integration into local energy management and billing systems
Key specifications
 Supply system: three-phase 3x230/400 V
 Rated current: 100 A (direct connection)
 Measurement type: active energy per phase
 Mounting: panel or DIN-rail compatible enclosure for distribution boards
 Display: front-facing numeric/indicator display for consumption readout
 Accuracy: class suitable for billing and monitoring (refer to official technical documentation for precise class and tolerances)
 Connection: fixed terminal connections for phase and neutral conductors
How to use
Install the meter into the distribution panel following local electrical codes and standard safety procedures. Provide supply connections to the three phases and neutral according to the wiring diagram supplied with the device, and ensure the device is tightened and secured in the panel. After power-up, verify the display indicates voltage and registers active energy. Use the front display to read cumulative energy per phase; connect to external monitoring or billing systems if interface options are available and required. Regularly inspect wiring and terminal tightness as part of routine electrical maintenance.
Usage recommendations
Ensure installation and commissioning are performed by a qualified electrician. Verify system parameters—voltage, frequency and load—match the meter's rated specifications before connection. For accurate long-term readings, avoid overloading above the rated current and perform periodic verification against a calibrated reference if used for billing or contractual measurement.
